The players have been suspended indefinitely, Alabama coach Nick Saban said in a university statement.

"The young men charged are indefinitely suspended as we continue to
gather information and talk to the appropriate people," Saban said. "The University
and football program have strict guidelines regarding issues of this
magnitude. This behavior is unacceptable for any student-athlete at the
University of Alabama and not representative of our football program."

According to arrest warrants (PDF), Pettway, Williams and Hayes attacked and robbed two UA students, Samuel Jurgens and Caleb Paul.

The
trio is accused of physically attacking Jurgens with “punches to the
head and face” and kicks to the ribs and back and stealing his backpack,
which contained an Apple MacBook Pro. Jurgens was knocked unconscious
and was treated for several cuts, a mild concussion and severe swelling.

Both Hayes and Williams confessed to committing the crime, according to the arrest warrant.

In
a separate incident, Williams physically attacked Paul with “punches to
the head and face” while Hayes and Pettway waited in a car “with
knowledge of Williams’ intent.” Williams came away with Paul’s wallet,
which contained cash, a UA student action card and various credit and
debit cards.

Williams later used Paul’s UA card and debit card to purchase snacks from a vending machine on the first floor of Bryant Hall.

With
knowledge that it was stolen, Calloway, who was not involved in the
robberies, admitted to using Paul’s UA card for numerous purchases.

Calloway acknowledged the incident in a reply to one of his followers on Twitter.

"first
it wasn't a credit card and 2 I wasn't even awake during the robbery
you don't kno what happened so dont try me dude," Calloway wrote.

UAPD received reports of the two
robberies early Monday. The first happened around 12:35 a.m. in the 800
block of Campus Drive and the second happened around 1:20 a.m. in the
200 block of Seventh Avenue, UA spokeswoman
Cathy Andreen said in a statement Tuesday morning.

UA police posted an advisoryMonday on the UAPD website about the robberies with details and descriptions of two suspects. An update followed that

Williams, a former five-star recruit from Panama City, Fla., did not play in 2012.

Hayes, a Thomasville native, played in 13 games as a reserve and had 14 tackles.Pettway
(Pensacola, Fla.) redshirted the 2011 season before playing a prominent
role as a pass-rushing defensive end in 2012. He had four tackles for
loss and 2.5 sacks this past season.

This
is Calloway's second arrest since he signed with Alabama in 2011. The
former Russellville standout was charged with second-degree possession
of marijuana in Oct. 2011. After redshirting his first season at
Alabama, Calloway played primarily on special teams in 2012.

"This is a very serious matter and we are very disappointed in the
actions that have resulted in the charges against these
student-athletes," Alabama athletic director Mal Moore said in a university statement. "In this type of situation, the Athletics Department
works in conjunction with the University. We will have more to say at
the appropriate time."
